Naming evolution's winners and losers

A new study by UCLA scientists reveals that mammals and many bird species have exceptional rates of success, while crocodiles and the tuatara have much lower species richness. The research analyzed DNA sequences and fossils from 47 major vertebrate groups to calculate which animal lineages have exceptional rates of success.

Easy assembly of electronic biological chips

Researchers create handheld device to recognize and report on environmental or medical compounds using biologically tagged nanowires and integrated circuit chips. The method allows for accurate placement of nanowires with less than a micron accuracy, enabling simultaneous detection of different pathogens or diseases.

Part of the in-group? A surprising new strategy helps reduce unhealthy behaviors

Researchers found that associating binge drinking with graduate students reduced junk food consumption by 28%. Linking unhealthy behaviors to an 'outgroup' can be a successful strategy for improving consumer health. By shifting perceptions of identity associated with risky behaviors, better health outcomes can be achieved.

It don't mean a thing if it ain't got that (modern) swing

A Duke University study found that female white-crowned sparrows prefer newer versions of their love song, indicating a shift in mate selection and territorial behavior. The researchers used controlled laboratory tests to assess bird responses to different song versions, revealing subtle yet significant differences.

UCR researchers examine how some invasive plants gain a foothold

Researchers found that controlling sexual compatibility in self-incompatible plants like the California wild radish can help minimize their reproductive success and prevent establishment. Larger population sizes and genetic diversity also boosted reproduction, highlighting potential strategies to combat invasive plant spread.

With fruit fly sex, researchers find mind-body connection

New research by Brown University biologists debunks the notion of separate genes controlling sexual behavior and physical body differences. Doublesex gene plays a crucial role in regulating both male and female courtship behaviors, acting together with fruitless to establish wing-shaking come-ons and flirtatious flights.
